Oral & Poster Presentation Abstracts Katheryn Adam, Chemistry Faculty Mentor: Marco Bonizzoni, Chemistry An off-the-shelf sensing system for physiologically relevant phosphates We have developed a chemical sensing system that can differentiate biologically relevant phosphates (nucleoside diphosphates, pyrophosphate) in neutral water solution using only commercially available components. Our approach uses a common fluorescent indicator and a poly(amidoamine) (PAMAM) polycationic receptor to construct an indicator displacement assay (IDA). The system crucially relies on multivariate data collection and analysis. In fact, using different phosphates in the dye-displacement assay results in subtle differences in the optical signals; however, it is not possible to capture this information using classical univariate data presentation techniques. Instead, we rely on principal component analysis, a multivariate data analysis technique, to evaluate these differences and thus distinguish between the biologically relevant phosphates. We will also present supporting data reporting on the anion binding capabilities of the PAMAM system acquired using optical spectroscopy methods. Alison Adams, Biological Sciences Faculty Mentor: Laura Reed, Biological Sciences QTL affecting genotype-by-diet interactions of larval triglyceride levels Metabolic Syndrome (MetS) is a complex disease that is becoming increasingly prevalent in the world today. It is identified by an assortment of symptoms such as obesity, insulin resistance, and elevated blood lipids. This disease and its various phenotypes can be modeled in Drosophila melanogaster. In a previous study of MetS, our lab implemented a round-robin crossing scheme on approximately 800 isogenic lines from a recombinant inbred line population, and a linear regression was used to determine genotype, diet, and genotype-by-diet interactions. Statistical analysis revealed quantitative trait loci (QTL) associated with larval triglyceride levels. Here we report on the functional analysis of genes within the QTL significant for gene-by-environment interactions through differential gene expression and the testing of mutant triglyceride levels. Ashley Alexander, Biological Sciences Faculty Mentor: Stephen Secor, Biological Sciences Testing the Cooking Hypothesis in Human Evolution Cooking of food has been hypothesized to have had a significant impact on human evolution. Cooking softens food thereby reducing the time and energy of chewing and digestion, therefore more food can be consumed at a lower cost, and more energy can be allocated to growth and reproduction. We tested this hypothesis by feeding raw and cooked sweet potato and carrot to the omnivorous bearded dragon (Pogona vitticeps) and measuring the effort of chewing and the cost of digestion. Pieces of raw sweet potato and carrots required 3 and 4 times more chews, respectively, than pieces of cooked. Both raw vegetables also required twice the time of digestion compared to cooked. Using closed system respirometry, we determined that lizards expended 40% more energy digesting raw sweet potato and carrots compared to cooked. Our data demonstrate the energetic advantage of consuming cooked versus raw foods. Our findings support the hypothesis that the advent of cooking had a significant impact in human evolution.

Stress Testing a Fundamental Prediction in Game Theory A procedure and program was designed to test a particular strategic situation in which number effects are the primary factor expected to drive the behavior of the various test participants. A certain result is expected for any even number of players and a different result is expected with any odd number of players. The test was designed to test at what point the unintuitive nature of number effects causes participants to deviate from the expected outcome. The situation involved a prize that players must risk their initial endowment to pursue and whether or not they capture the prize or not is dependent on the actions of others. In an odd number of players situation, the players were expected to attempt to capture the prize in the first round but only the first round. In an even number of players game, it was expected that the Nash Equilibrium would have all players inactive in order to protect their initial endowments. Upon testing, it was discovered that for all but the simplest cases of the strategic situation, the expected Nash Equilibrium does not play out as anticipated but rather players exhibit a max-min behavior. Rather than acting according to the perfectly rational predictions, players, unaware of how the other players will act, choose to maximize their worst case scenario by choosing inaction unless they are the only player remaining in the situation. Liz Alley, Information Systems, Statistics and Management Science Spencer Baer, Computer Science Faculty Mentor: Felecia Wood, Capstone College of Nursing Diabetes101: an iOS application The purpose of this project was to develop a tool to improve health literacy and self-management skills in rural adults with type 2 diabetes. Many rural adults read at less than a high school level, which means that they probably struggle with reading most patient education materials. Diabetes101 is an iOS app that introduces users to fundamental concepts and terminology related to type 2 diabetes and self- management. The app was piloted at two clinics in Walker County, Alabama, and includes videos filmed in Walker County to help participants see "people like them" effectively managing diabetes. The videos address shopping, cooking, collaborating with health care providers, engaging in physical activity, and coping with the emotional challenges of living with type 2 diabetes. Brief quizzes assess diabetes knowledge. A dictionary introduces medical terminology. And an exercise assessment provides guidelines for engaging in physical activity. Samuel Andersen, Biological Sciences Faculty Mentor: Chelley Alexander, Community Health Sciences The impact of lay worker education on the frequency of ER visits and hospitalization and use of preventive medication and rescue inhalers in asthma patients The direct and indirect medical cost attributed to asthma in the US last year was over $50 billion. Many interventions have been proposed to bring down this cost, however the issue seems far from solved. Though there is no cure for this condition, medications such as inhaled corticosteroids exist and are capable of preventing asthma attacks if taken properly. The National Heart, Lung and Blood Institute care guidelines recommend physicians provide their patients with a written action plan as a part of checkups, yet one survey showed that as few as 25% of physicians comply with this recommendation. To address this situation, this prospective, year-long study seeks to answer the question: can a cheap and simple intervention be found to bring down the cost associated with asthma and improve patient quality of life? Symptom-based written action plans will be administered to study participants by lay people (University of Alabama students, in this study) and benchmarks such as trips to the emergency department as well as number of refills on controller and emergency medications will be monitored over the course of a year. 2 *The information presented here is intended to represent exactly what was submitted by the student.

Ali Anderson, Capstone College of Nursing Emily Bates, Capstone College of Nursing Lindsey Badham, Capstone College of Nursing Jeremy Blount, Capstone College of Nursing Faculty Mentor: Paige Johnson, Capstone College of Nursing Childhood Obesity: An Interactive Approach for Parents & Children Health promotion is the process of enabling individuals to gain control over and improve their health. It goes beyond a focus of individual behavior towards a wide variety of social and environmental interventions. The purpose of health promotion is to increase the wellbeing of the individuals in the community by teaching positive life style changes. These changes will influence all aspects of the individual's health. In order to implement these health promotion behaviors, the community must be assessed to identify risk factors and resources needed to evaluate and improve health. A community assessment is achieved through systemic collections which include windshield surveys, observations, and interviews with community members. This data is then analyzed to determine the specific needs of the community. Interventions supported by evidence-based practice are then implemented to promote the particular health care needs of the community. This presentation will demonstrate a community assessment of Duncanville, AL in Tuscaloosa County. Features such as resources, needs, and demographics are shown to identify the problems of the community. The major health concern is identified, and the intervention is supported by evidence-based practice to address the main concern. Travis Atchley, Chemistry Faculty Mentor: Silas Blackstock, Chemistry Donor-Acceptor Cocrystallization for Molecular Assembly The synthesis of donor-acceptor cocrystals is of valuable interest in organic chemistry to probe the nature of attractive interactions between molecules. Some instances of cocrystallization lead to unexpected, yet intriguing, results in terms of special electronic interactions between the donor and acceptor components and the resulting macroscopic electronic properties of the cocrystal that may result. Two such instances are found in the cocrystallization of phenyl-substituted pyrazoles, DPOX and 4HP (e-donors, D) with the e-poor quinone, DDQ (pi* e-acceptor, A). The binding of these molecules yields D2A cocrystals that feature lp*/pi*/lp* D-A-D triads. The packing of these triads lead to in-plane assembly of DDQ molecules and pi-stacking of the donors in the cocrystal solid. Parker Baxter, Geological Sciences Faculty Mentor: Joe Lambert, Geological Sciences How Stalagmites are Used in Paleoclimate Research in the Southeast (USA) Many unanswered questions exist with respect to predicting changes in regional rainfall patterns over the next 50-100 years because of the complexity of the Earth's climate system and our limited understanding of how global climate change will affect particular areas. In the Southeast, it is vital that we try to understand changes in future rainfall because rainwater is the sole source for recharging surface and subsurface reservoirs, which are continuously used for drinking water in addition to agricultural, industrial, and recreational needs. In an effort to better understand climate change, scientists are researching periods of climate variability over the past several thousand years. Archives of past climate conditions include, but are not limited to, cave deposits, lake and ocean sediments, ice sheets, and ancient trees. Cave deposits, such as stalagmites, can be dependable climate archives because they (i) preserve various proxies for past climate conditions (eg., rainfall amount) outside the cave, (ii) have the potential to provide long and continuous high-resolution records, and (iii) can be accurately dated by multiple methods. Over the past decade, our research group has been developing paleo-rainfall records for the Southeast from multiple stalagmites collected from two caves in Alabama. 3 *The information presented here is intended to represent exactly what was submitted by the student.

In this presentation we will introduce this type of research, show our current interpretations from DeSoto Caverns, and discuss our preliminary results from Cathedral Caverns. Zach Beasley, Psychology Bryan Poole, Psychology (Lee Universtiy) Sydney Gruber, Psychology Faculty Mentor: Phillip Gable, Psychology Time Perception in Negative Affects: The Role of Motivational Direction Time flies when you're having fun, but how does time pass when you're upset? The current experiment investigated the impact of motivational direction in sad and anger states on time perception. In two experiments, we induced approach- and withdrawal-motivated sad (Experiment 1) or angry (Experiment 2) states. Participants wrote about a personal situation when they felt either approach- or withdrawal- motivated sadness or anger. After writing, they viewed a sad film (Exp 1) or anger film (Exp 2) and rated how long the film lasted. Results indicate that approach-motivated sadness and anger caused perceived time to pass more quickly than withdrawal motivated sadness. In two diverse negative states, these results support the conceptual model linking approach-motivated affective states to faster perceptions of time, and withdrawal-motivated affective states to slower perceptions of time. Jonathan Belanich, Biological Sciences Faculty Mentor: Stephen Secor, Biological Sciences Tarantulas vs. Scorpions: Digestive energetics and efficiencies of drinking versus eating The processing of any meal comes with a cost; a cost that impacts the net energy gained and therefore is incorporated into the efficiency by which energy is acquired. Within the class Arachnida, tarantulas are liquid feeders using oral mastication and enzymes to produce an ingestible liquid sludge, whereas scorpions masticate and ingest small pieces of their prey. To a common meal, crickets, and body temperature, 30C, we examined how two arachnid groups differ in the cost of meal digestion and net energy efficiency. For three species of tarantulas and five species of scorpions we measured their postprandial metabolic response and quantified their SDA, which represents the accumulative energy expended on meal ingestion and assimilation. Both groups experienced a rapid postprandial increase in metabolic rate that peaked within 6ˆ’12 hours after feeding and returned to prefeeding values within two days. Tarantula and scorpion SDA averaged 20.8 kJ kgˆ’1 and 42.2 kJ kgˆ’1, respectively, and each was highly dependent on meal size. We found that when controlling for meal energy, scorpions expend 80% more energy on digestion and assimilation compared to tarantulas, however the differences in their SDA were not significant. We suspect that the lower SDA for tarantulas reflects their more liquidˆ’like diet and less postˆ’ingestion effort. Alternatively, the cost of meal digestion may be more similar between the two when including the cost for tarantulas of mastication and enzyme production. Jonathan Belanich, Anthropology Faculty Mentor: Christopher Lynn, Anthropology Sex and Lies: A Study of Cultural Knowledge and Mating Success This study compares various indicators of mating-relevant self-deception and self-awareness to proxies of mating success. Self-deception, when looked at in the context of human mating, can prove to be a useful tool that may allow individuals to deceptively self-promote without displaying the "tells" that are indicative of lying. To test this, an online survey was created and publicized to get responses. We received a total of 120 responses from both males (N=45) and females (N=75), and had a wide age range (18-60+). The survey contained two parts: in the first responders were asked questions about previous sexual encounters and habits, and in the second responders were asked about their familiarity with cultural objects and people, such as beer, musicians and hobbies. In the second part, false items were 4 *The information presented here is intended to represent exactly what was submitted by the student. Errors can occur in the transfer process.
mixed in with the real ones. The amount of true and false positives is a measure of "overclaiming." Correlations were run to look at reactions between different variables, and from these, we were able to identify several significant interactions. Regressions were then run using overclaiming as the independent variable and indices of mating success as dependent variables. Results indicate correlation between the degree of overclaiming and the number of intercourse partners. Therefore it is possible that self-awareness when moderated by self-deception could improve chances of maximizing the total number of intercourse partners. Luke Bishop, Biological Sciences Faculty Mentor: Ryan Earley, Biological Sciences Revealing the Effects of Endocrine Disrupting Compounds on the Behavior and Physiology of Fish: Dose- Response Relationships In today's world, the environment is under a constant threat of damage from industry. A primary example of this is the mangrove habitat, a valuable ecosystem that is home to a wide variety of species and a breeding site for many marine fishes. However, wastewater treatment plant effluent, which contains many chemicals known as endocrine disrupting compounds, is threatening mangrove habitat. These chemicals can disrupt hormone levels and internal homeostasis of organisms exposed to them. Our experiment examines the effects of two such compounds (ethinyl estradiol and nonylphenol) on the behavior, physiology, and gonad morphology of the mangrove rivulus fish. These chemicals have dramatic effects on reproduction, anxiety-like behavior, and aggression. They can cause increased vulnerability to predation and decreased aggression in males. However, we know little about whether low versus high environmentally relevant doses of these chemicals have different effects on the fish. We thus propose to expose the fish to various doses of the endocrine disrupting compounds for a set time and ascertain the behavioral and physiological consequences of exposure. We will test the fish based on their aggression, boldness, fear response, and hormone levels. With the effects of the endocrine disrupting compounds studied and quantified, we can then determine the potential threat level to the mangrove ecosystem to ensure its safety and the safety of all its inhabitants. Ruth Bishop, Biological Sciences Faculty Mentor: Laura Reed, Biological Sciences The Roles of Endocannabinoids and Their Chemical Relatives in Drosophila melanogaster Metabolism Endocannabinoids are endogenous neuromodulatory lipids that bind to cannabinoid receptors. They are involved in lipid metabolism and appetite, making them and their chemical relatives interesting to study in the context of metabolic syndrome. Despite previous bioinformatic analyses of gene sequences suggesting that the cannabinoid system is absent in insects, we have found in metabolomic analyses that L-DOPA and N-arachidonoyl dopamine (NADA) levels are correlated with pupal weight, triglyceride levels, and total sugar levels; evidence pointing to these compounds' roles in Drosophila metabolism. We selected 6 compounds for this study, 2-AG, anandamide, L-DOPA, Dopamine HCl, capsaicin, and NADA, because they were either ligands to mammalian cannabinoid receptors or involved in dopamine or NADA synthesis pathways. We first conducted a dose response curve to determine if these compounds would negatively affect survivability. Finding no such effects, larvae from five genetic lines were fed 100 µM of these compounds to determine whether pupal weight, triglyceride levels, or glucose levels were affected. We found that these compounds had line specific effects on these phenotypes, although we did not find consistent phenotype changes across all genetic lines. Based on these findings, it is unclear whether endocannabinoids play a role in Drosophila melanogaster metabolism since these compounds did not consistently affect glucose/ triglyceride levels or pupal weight.

Faculty Mentor: John Lochman, Psychology Effects of the April 27, 2011 Tornado on Parental Functioning This research examines the way in which the tornado that devastated Tuscaloosa impacted the way parents function and interact with their children. The data was collected from families of moderate to highly aggressive children in Dr. Lochman's Coping Power Program. Changes in parental functioning were analyzed using the Alabama Parenting Questionnaire, The Beck Depression Inventory and the Caregiver Stain Questionnaire- Short Form. These measures were collected before and after the tornado and provide an assessment of change in parent's individual behavior as well as parenting behaviors. Results indicated that parents felt less caregiver strain after the tornado than before, but that that there was no significant change in types of parenting or parental depression over time. After the tornado parent's poor parenting was more related to low levels of inconsistent discipline and poor parental monitoring than before the tornado. Implications of these results will be discussed. Joshua Blackwell, Biological Sciences Faculty Mentor: Juan Lopez-Bautista, Biological Sciences Digitizing the algal herbarium of The University of Alabama Authors: Joshua Blackwell, Frederik Leliaert, Steve Ginzbarg, Juan Lopez-Bautista Natural history collections serve a highly important purpose in the scientific community. Algal herbaria, in particular, contribute significantly to the identification and classification of specimens, and act as a record of morphology, evolution, and geographical distribution of species. Specimens housed within herbaria can also be used to acquire molecular data, which is the basis of genomic analysis. As such valuable resources, it is vital that the contents of University collections such as algal herbaria be digitized, and thereby made available to the public. Only when information becomes accessible can it become useful for researchers, educators, and students. Prior to the current project, the University of Alabama has not published information regarding any of the algal specimens contained within the herbarium. The University's collection contains over 1000 specimens of green, red, and brown algae, including many deep-water specimens (down to 50 m) from the Gulf of Mexico. These collections are especially valuable to study shifts in species distributions resulting from increased anthropogenic activity in this region. The goal of the current project is to database this material, making digital information and images available on the University's herbarium website, as well as the Global Biodiversity Information Facility (GBIF) website. Emmie Bodiford, Journalism Faculty Mentor: Chip Brantley, Journalism Anatomy of a Trial Anatomy of a Trial is a service learning class introduced to the University of Alabama in 2013 by professors Chip Brantley and Andrew Grace. The class consists of seven undergraduate and graduate students interested in exploring the Alabama Justice system. Through the context of one capital murder case from 1980s, information concerning the structure and processes of the Alabama Justice system was compiled through a group effort. The findings highlight unique aspects of various problems with the current Alabama justice system as well as changes it has experienced over the past several decades. Hannah Bowers, Chemical and Biological Engineering Faculty Mentor: Margaret Liu, Chemical and Biological Engineering High-Level Expression of Targeted Anti-Cancer Biopharmaceuticals Using CHO Cell Chinese Hamster Ovary (CHO) cell, the most popular mammalian cell used in the biopharmaceutical industry, was used to develop a production cell line to express the targeted anti-cancer therapeutic 6 *The information presented here is intended to represent exactly what was submitted by the student.

protein. Lonza GS vector system was applied to construct the over-expression plasmid of monoclonal antibody IgG1 for high-producing CHO K1/IgG cell line construction. The methionine sulfoximine (MSX) amplification and glutamine-free selection were performed to select and amplify IgG production. Multiple single clones were obtained using limiting dilution cloning, producing about 350-800 mg/L of IgG. The glycosylation of produced protein will be analyzed to define the lead clone for the process development of anti-cancer biopharmaceutical production. Leah Bradford, Telecommunication and Film Drew Bryant, Telecommunication and Film Taylor Crosby, Telecommunication and Film Sarah Hollingsworth, Telecommunication and Film Faculty Mentor: Chandra Clark, Telecommunication and Film City of Alberta: Looking to the Future Along with the citizens of Alberta, our team is working to re-brand the community. After the devastation of the April 27th tornado, Alberta was left destroyed but the community has a lot on its horizon! This spring, Tuscaloosa Parks and Recreation Authority will break ground on the new tennis complex that will have numerous courts and host tournaments from around the country. Later this year, the new Alberta School will be opening and will specialize in fine arts education. With the help of Councilman Kip Tyner, our team is constructing new websites and social media sites to bring Alberta to the forefront of the Tuscaloosa area. We are working to give the community of Alberta an outlet to use for updates and information about the area using videos on the website. Using Instagram and Vine, we are able to promote upcoming events such as business openings and ground-breakings. My team and I are working as Alberta's unofficial marketing team using our experience and knowledge about social media and community interests. Our team communicates with our client, officially listed as Kip Tyner, weekly to assess our progress and what is needed for the community project. This week alone we are meeting with Mayor Walt Maddox and the Alberta community to present our developments and will present the final product later this month. Travis Brady, Aerospace Engineering and Mechanics Faculty Mentor: Vinu Unnikrishnan, Aerospace Engineering and Mechanics Computational Modeling of Normal and Cancerous Cells The purpose of this study is to determine the various mechanical properties of a nonhomogeneous eukaryotic cancer cell. While the cell itself is nonhomogeneous, it can be divided into three homogeneous regions (nucleus, cytoplasm, actin cortex) to simplify the analysis. The homogenous properties of the various regions of the cell are obtained using mathematical homogenization techniques and are then analyzed using finite element analysis. Various indentation conditions are simulated and the deformation profile of the cell is obtained. The ultimate aim of this study is to understand and compare the deformation profiles of various types of cancerous cells and normal healthy cells. Such a study would be helpful in identification and prevention of cancerous cells throughout the circulatory system of the human body. Hannah Brewer, Psychology Faculty Mentor: Karen Salekin, Psychology Juror Perception of Culpability and Its Impact on Verdict and Sentencing: Defendants With and Without Intellectual Disability In 2002, the United States Supreme Court decided that offenders with intellectual disability (ID) could not be executed due to their reduced level of culpability (Atkins v. Virginia, 536 U.S. 304 2002). Previous studies show that jurors view defendants with ID as less culpable than their non-disabled counterparts 7 *The information presented here is intended to represent exactly what was submitted by the student.

(Garvey, 1998; Najdowski & Bottoms, 2012). This study looked at intelligence quotient (IQ) and adaptive behavior (AB) deficits to see if they factored into jury decision-making regarding level of culpability for defendants with ID and those who barely miss the cut score(s) for ID using 544 jury-eligible college participants recruited from a psychology department subject pool. Participants were presented with a vignette of an altercation resulting in a charge of aggravated assault in which IQ and onset of AB deficits of the defendant were manipulated. Participants then completed a questionnaire measuring (1) culpability, (2) ratings of IQ and AB deficits, and (3) weight of factors on sentence. It was found that IQ but not age of onset of AB deficits impact how jurors perceive culpability of defendants and having an IQ below the bright line standard of 70 increases the likelihood that a defendant will be found not guilty or not guilty by reason of insanity. Further research should be conducted to determine what factors other than IQ and AB lead jurors to believe that ID or borderline ID defendants are less culpable than their non-disabled counterparts. Christian Brewton, Computer Science Anna Zimmerman, History Faculty Mentor: Stephen Lovell, Computer Science Determining the Mood of Someone Through Facebook Feeds The purpose of this research topic is to assay the messages someone posts on Facebook to compute their mood. By using the Facebook API and Facebook Query Language (FQL) one is able to parse through a user's Facebook messages and pick out keywords and weight them accordingly to try to get an accurate percentage of what mood he or she is in. Facebook emoticons can also be quite helpful because one can get a pretty accurate idea of what mood the Facebook poster was in at that time. This idea can be expanded to even calculate your friends moods, and the user can get an idea of what he or she's friends are feeling. Moods can be spread through Facebook in the same way that mood can spread through human interaction. According to researchers happiness tends to spread more efficiently than any other mood. John Brinkerhoff, Communication Studies Faculty Mentor: Jason Black, Communication Studies The World's Great Father: Paternalistic Rhetoric's Continuities in U.S. Presidential Interventionist Discourse This essay explores the rhetorical continuities of paternalistic rhetoric within the addresses that surround two key interventions in U.S. history: Andrew Jackson's first three Annual Messages to Congress, which sought to advocate and defend the Indian Removal Act, and Truman's Address before a joint session of Congress on March 12, 1947, which proposed what would later become known as the Truman Doctrine. Both interventions, as well as the legitimation tactics behind them, were foundational in the formation of U.S. foreign policy. This study contends that their use of paternalistic rhetoric created a foundation of paternalism at the core of U.S. foreign policy both historically and contemporarily. This essay identifies similarities in their use of paternalistic rhetoric through its identity constructions of a self/other dichotomy that legitimizes intervention by the self to assist a helpless other. This dichotomy coalesces into four key components: Self as Father, Self as Benevolent, Other as Weak, and Other as Facing Crisis. This study argues that these themes, when taken together, have created a prominent strand of rhetoric that has remained consistent in presidential intervention addresses, even as the surrounding contexts shift. Cole Buchanan, Biological Sciences Faculty Mentor: Glenn Davis, Community Health Sciences Investigating the Effects of Fatigue in Emergency Medical Service Providers 8 *The information presented here is intended to represent exactly what was submitted by the student. Errors can occur in the transfer process.
Emergency Medical Service Providers provide out-of-hospital medical care in emergency situations. The majority of Emergency Medical Technicians (EMTs) in the state of Alabama routinely work 24 hour shifts, sometimes consecutively. Our purpose is to determine if the quality of EMT performance late at night is different from the quality of EMT performance during the day. The initial stage of this study consisted of an electronic survey sent to EMTs statewide to determine their perceptions of the effects of fatigue on performance. Data gathered from the survey included information on demographics, sleep patterns, use of stimulants on and off shift, and perceptions of how fatigue affects quality of care at different times during a 24 hour shift. To expand on the findings of this survey, a study was developed utilizing performance based trials to compare performance of paramedics from Tuscaloosa Fire and Rescue Services in the morning to their performance late at night. Trials measured basic skills including intubation and CPR performance in a simulated medical emergency. Data from these trials provides insight into the quality of care given by EMTs over the course of a 24 hour shift. Katy Buddemeyer, Biological Sciences Faculty Mentor: Stephen Secor, Biological Sciences Negative Calorie Food: Fact or Fiction? Though countless online sources claim that certain foods are "negative calories," requiring more energy to digest and assimilate compared to calories absorbed, there have been no scientific studies to support or refute this assertion. To assess the validity of this idea, we fed celery, a noted "negative calorie food," to omnivorous bearded dragons (Pagona vitticeps) and quantified the caloric intake, energy expended in consumption and digestion, and the assimilation efficiency in order to determine the net gain of energy. Lizards assimilated ~70% of ingested celery calories and expended ~90% of that energy on digestion and assimilation. Celery intake therefore resulted in a small net gain of energy, challenging the widespread claim that celery is a negative calorie food. Alex Bullough, Capstone College of Nursing Paul Brooks, Capstone College of Nursing Morgan Buko, Capstone College of Nursing Meagan Busby, Capstone College of Nursing Faculty Mentor: Paige Johnson, Capstone College of Nursing Educating Brookwood about Nutrition Nutritional education is the process of teaching a specified group the importance of a healthy diet. Nutritional education promotion is a positive way to influence the community. Interjecting our positive nutritional views into an extremely tight-knit community requires a trusting medium, such as the local church organizations. Establishing rapport with a very involved member of the church community can aid us in spreading the word of healthy eating and good nutrition. Nutrition affects all aspects of life. It is extensively involved in many disease processes, preventable and inevitable. A change in nutrition can help drastically change the health of individual. Helping the community understand nutrition's importance and benefits in their daily lives will encourage them to make positive changes. Our community health project will focus on educating the adult population in a comfortable and safe setting about healthy eating. David Burkhalter, Civil, Construction and Environmental Engineering Faculty Mentor: Milton Ward, Biological Sciences Analysis of The Potential Ecological Impact of Controlled River Water Withdrawals on Floodplain Ecosystems Using 3D Modeling Our nation's food supply is currently heavily dependent upon crop production in the West. Production in this arid climate, however, depends heavily on irrigation from snow melt high in the Rocky Mountains. 9 *The information presented here is intended to represent exactly what was submitted by the student. Errors can occur in the transfer process.
Many future climate scenarios indicate less snowfall in the West, and therefore, reduced availability of irrigation water. To reduce the ensuing economic spike, an alternative proposal is to capture and utilize the high winter flow in the rivers of the southeastern US, and create an agricultural environment that is more resilient to the drought seasons. This research explores the feasibility of withdrawing excess river water and storing it offline for summer use. It also considers the ecological impact of withdrawal on hydrologic regimes in rivers and the environmental consequences of withdrawal on adjacent floodplains that depend on river floods. This study was designed to examine potential impacts of four river-floodplain environments in the Southeastern US. Using USGS flow data and NOAA LiDAR data for each site, we built a 3-D computer generated hydraulic model to predict the frequency, extent, and duration of flooding. These models produced inundation maps that illustrated the relationship between flow rates and inundation extent. Through analysis of these maps, we may more accurately understand the ecological consequences of water withdrawal scenarios on our river systems. Maranda Burns, Chemistry Faculty Mentor: David Dixon, Chemistry Comprehensive Study of the Bond-dissociation Pathways for Glycine and Alanine Dipeptide Anions and their Corresponding Amides Computational studies of bond-dissociation pathways in small anionic peptides have been performed to determine the bond energies of the backbone bonds. The reaction enthalpies of glycine, alanine, diglycine, and dialanine anions and their corresponding amides have been calculated using the reliable correlated molecular orbital theory G3MP2 method to determine the lowest energy dissociation pathways. Extensive conformational sampling of the neutral and anionic fragments was performed using density functional theory (DFT). In all cases, a rearranged BDE that results from the fragmentation of CO2 is the lowest energy pathway and all other pathways are higher in energy by ~ 30 kcal/mol. Gregory Cabot, Electrical and Computer Engineering Vaishali Batra, Electrical and Computer Engineering Samantha McPeak, Electrical and Computer Engineering Faculty Mentor: Sushma Kotru, Electrical and Computer Engineering Labview Programming for Research Analysis LabVIEW programming is a graphical programming language commonly used for automated data collection in a research environment. In this project, LabVIEW programs were created and used to measure and record data for several research projects. The measurements included, but were not limited to, temperature effect on resistivity of various electrode materials; current-voltage measurements and photovoltaic response of PLZT thin film based solar cells. Results obtained on the use of seed layer to enhance the photovoltaic response of PLZT film based solar cells will be presented. Emily Capps, Psychology Faculty Mentor: Tricia Witte, Human Development and Family Studies The Mediational Role of Marital Conflict in the Associations Between Parental Problem Drinking and Children's Social Information Processing Marital conflict and parental problem drinking has a strong link with children's maladjustment. The objective of this study is to examine the effects of these variables on children's social information processing. Around 60 participants will be brought in for this study through magazine subscription databases, the local YMCA, and from Dr. John Lochman's Coping Powers group. Parent participants will be completing questionnaires measuring level of marital aggression with the subscale of psychological aggression. They will also be completing questionnaires about their daily drinking and also their drinking 10 *The information presented here is intended to represent exactly what was submitted by the student.

within the past year. Child participants will be completing questions regarding certain vignettes; those of which contain ambiguous provocations. The dependent variables we will be examining are children's hostile attribution biases, hostile goals, and aggressive strategies. The results of this study will help future intervention methods regarding aggressive children. Leighton Carlock, Religious Studies Faculty Mentor: Steven Ramey, Religious Studies Myth as Illusion *International focus The Ramayana is a story popular in India with many different tellings, but people across the globe have interpreted it in various ways. In this research, I analyze three stories of Ramayana: the English interpretation of Valmiki Sanskrit version, a comic book telling from Dreamland Publications, and the story of Rama from the Warner Brothers film A Little Princess. My analysis focuses on each story's telling of the abduction of the beloved Sita by the evil demon, Ravana. Through critical analysis, I compare each of the three different interpretations. Ultimately, this research will show religious tellings as interpretative and highlight political, social, and cultural biases incorporated in interpretation from authors and readers, challenging this contemporary thought of the "correct" and "true" telling because there is not one authoritative version of this story that exists. Michael Carton, Metallurgical and Materials Engineering Faculty Mentor: Su Gupta, Metallurgical and Materials Engineering Combined interface and bulk anisotropy free layers for MgO based MTJ We have investigated the effect of Ta insertion thickness on perpendicular magnetic anisotropy (PMA) in [Co/Pt multilayers]/Ta/CoFeB (hard/soft) composite free layer. We observed increase in PMA with increase in Ta insertion thickness. We found that this increase of the effective anisotropy is associated with bulk-type PMA of multilayers and enhancement of CoFeB/MgO interface anisotropy with Ta insertion thickness. The interface anisotropy increased by more than 0.9 mJ/m2 as the Ta insertion thickness increased from 0 nm to 0.5 nm. For insertions less than 0.6nm thick, the ferromagnetic exchange was strong enough to switch the two layers together. The interlayer exchange coupling changed from ferromagnetic to anti-ferromagnetic in nature for Ta insertion thicknesses above 0.7nm. The Hk value for the composite free layer with 0.5nm thick Ta insertion was around 11 kOe, leading to a high thermal stability factor, estimated around 152 for 20 nm nanodots. A micromagnetic model was set up to study the effect of interlayer exchange coupling on switching current density and switching time. The ab-initio calculations for Fe/MgO and Fe/Ta interfaces were performed for parameterization of the micromagnetic model. We found that the switching current density increased with increase in the coupling parameter, and thus the Ta insertion layer was not expected to degrade spin-torque transfer (STT) switching characteristics. Cole Cecchini, Biological Sciences Faculty Mentor: Debra McCallum, Institute for Social Science Research Helping Children Make Healthy Food Choices: Progressive Agriculture Safety Day Program In response to high rates of obesity among rural youth, Progressive Agriculture Foundation (PAF) has begun an initiative through their safety day program to improve the diets of elementary school children by educating the students on overall healthy lifestyles and changing their school food environment to encourage healthy choices. The project was implemented through PAF Farm Safety Days held at five test sites and five control sites in rural southern communities. During the safety days, youth attended sessions on various safety and health topics. In the test sites, one of these units focused on healthy eating. Also, in test sites a 11 *The information presented here is intended to represent exactly what was submitted by the student. Errors can occur in the transfer process.
workshop was conducted for adults to develop a strategic improvement plan (SIP) aligning the educational outreach with concrete local goals to improve the school food program and track progress toward those goals. To evaluate the project, students completed pre- and post-tests before and after the safety day. One year later, they will complete a follow-up test, and the test sites will be visited by researchers to evaluate progress toward SIP goals. Data collection will be completed in spring, 2014, and test sites will be compared to control sites that had no healthy eating lesson and no workshop. Results will indicate whether goals outlined in the SIP were met and the impact the program had upon the participants. If this pilot project is found to be effective, PAF will expand the program to include other rural communities. Sarah Chaffee, Human Nutrition and Hospitality Management Emily Huie, Human Nutrition and Hospitality Management Hannah Rath, Human Nutrition and Hospitality Management Cassidy White, Human Nutrition and Hospitality Management Faculty Mentor: Lori Greene, Human Nutrition and Hospitality Management Effects of Community Based Garden Intervention on Fruit and Vegetable Consumption in Children: A review Background: One of the leading causes of premature death in the US is low fruit and vegetable intake. Food preferences developed during childhood have been shown to have a great effect on food habits for life. Purpose: To determine the effect of community garden based interventions on fruit and vegetable consumption among children. Methods: Scientific databases were searched for relevant articles. Our inclusion criteria comprised of articles that were focused on children, fruit and vegetable intake, and studies examining the effect of exposure to community gardens. Results: Gardening programs have been shown to promote intake, availability, and preference for fruits and vegetables. Groups of children who received nutrition education as well as garden experience showed higher preferences and consumption of fruits and vegetables and increased nutrition related knowledge. Programs which involved parents showed increased availability of fruits and vegetables in the home. Several surveys demonstrated support for community garden programs. Conclusion: Community garden based nutrition interventions have been shown to be effective in promoting fruit and vegetable intake among children which could decrease nutrition related health disparities and improve overall health status in the future. Siddhartha (Neil) Chakraborti, Economics, Finance and Legal Studies Zhechen Yu, Culverhouse School of Accountancy Faculty Mentor: David Ford, Management and Marketing Impact Fees Study This project seeks to determine the use, basis, rationale, and potential benefits of implementing an impact fee for the city of Tuscaloosa, Alabama. The project and presentation is divided up into three basic phases. In the first phase, we define the impact fee, and discuss some theoretical implications, and what local officials have determined as the most urgent needs for their individual departments and if and how the impact fee can fix these. Next, we survey other cities and state governments that already implement impact fees to understand their rationale, structure, and calculation. Finally, we attempt to develop a hypothetical impact fee structure for Tuscaloosa.

Tenisha Lynch, Psychology James Cranford, Psychology Kristy Shoji, Psychology Faculty Mentor: Natalie Dautovich, Psychology Tossing and Turning: The Role of Anxious Arousal in Sleep Outcomes Background: Many factors are involved in obtaining restorative sleep. Excessive arousal, which can occur both physically and psychologically, is often implicated in poor sleep. The purpose of the present study was to investigate the association of physiological arousal with multiple sleep variables. Methods: An archival analysis was conducted using data from 314 adults participating in the Midlife in the United States-II study. Participants completed the Mood and Symptoms Questionnaire (MASQ) about the prior week. The anxious arousal subscale of the MASQ was used as a measure of arousal. Participants also wore actiwatches and completed sleep diaries for seven days. Results: Bivariate correlational analyses showed that anxious arousal was significantly correlated with the sleep diary variables of: sleep onset latency, r=.22, p
Possibly one of the most important discoveries in recent paleoanthropology, a finger bone and millions of base pairs decoded from ancient DNA support the uncovering of a new hominid species known as Denisovans that are claimed to have interacted with Neanderthals and Humans across Eurasia. Catherine Cofer, Chemistry Faculty Mentor: Marco Bonizzoni, Chemistry Solubilization of hydrophobic molecules by hyperbranched polyelectrolytes Dendrimers are highly branched polymers that have been shown to increase the water solubility of otherwise insoluble organic molecules. In particular, we have shown that poly(amidoamine) (PAMAM) dendrimers have the ability to preferentially increase the water solubility of hydrophobic aromatic molecules. In order to prove this concept, we have conducted the dendrimer mediated extraction of anthracene, a fluorescent aromatic hydrocarbon, from an organic solvent into a buffered neutral aqueous solution. The phase transfer was monitored using fluorescence emission spectroscopy. The increased fluorescence intensity of the water phase indicates that the anthracene molecules have been transported from the organic to the water phase. Here we will first present results confirming the dendrimer's preference for aromatic substrates, and the results from the extraction experiments. We will also outline the work currently in progress in our group aimed at quantifying these interactions through liquid membrane extraction experiments. Ian Connell, Music Faculty Mentor: Andrea Cevasco, Music Hospice Music Therapy and The Six Domains of Human Experience Music therapy (MT) is a multi-faceted healthcare profession that helps people cope with life and life events. Hospice and palliative care (HPC) focus on improving quality of life (QOL), relieving pain and distress at the end of life. The field of hospice music therapy has grown vastly in the past two decades, and continues to grow as its benefits are documented. There are six domains in which MT can benefit those in HPC settings: motor, cognitive, communication, social, emotional, and spiritual. By addressing the unique needs of those receiving HPC in the final months of life, music therapists can improve QOL using various MT techniques to benefit each of those six domains. Keisha Cook, Mathematics Faculty Mentor: Elizabeth Wilson, Educational Studies in Psychology, Research Methodology and Counseling The Relationship Between African American K-12 Perceptions and Their Participation in STEM Fields The purpose of this study is to examine the relationship between African American perspectives and their participation in STEM fields. Within the category of African Americans in STEM fields, less females are represented than males. In my study male and female perspectives will be examined separately to determine the difference between the genders. The importance of this study is to examine if there is a relationship between African American perceptions and choosing STEM fields. The objective of this research is to examine the perspectives that African Americans have towards STEM fields that affects their decision to pursue STEM fields. The main research question is the following: What factors support and/or hinder African American participation in STEM fields? To answer this question, the data will examine internal motivations, external influences, initiatives and programs that affect the decisions of African Americans pursuing STEM fields. I hypothesize that students who have positive motivators, influences and experiences will be more like to pursue STEM fields, than students who have negative motivators, influences and experiences. By understanding the negative and positive factors, a change can be made in K-12 education. This research will add a better idea of how to 14 *The information presented here is intended to represent exactly what was submitted by the student. Errors can occur in the transfer process.

Molly Cook, Biological Sciences Faculty Mentor: Ryan Earley, Biological Sciences Prey Response to Predation Risk in Acidified Environments Acidified environments are the result of human-induced elevation of greenhouse gases (carbon dioxide) and pollutants (sulfuric acid). In unexposed environments, fish are able to sense chemical cues that alert them to predation risk, allowing them to flee without being preyed upon. This may be due to the presence of a cell within the epithelium of prey species called a club cell that when punctured, releases a chemical to signal other fish in the area that a predator is successfully hunting. When a fish senses either a predator cue or a club cell signal, it employs several tactics to escape or become less conspicuous such as fleeing or freezing. In acidified environments, the ability to identify such cues as being harmful becomes inhibited by altering the Cl- and HCO3- gradients in the brain causing GABA receptors to become excitatory (instead of inhibitory). Such neurochemical changes inhibit fleeing behavior and may even cause predator approach behavior. Our project first confirmed the presence of epidermal club cells in mangrove rivulus, which never have been recorded in this fish or its family. We then compared epidermal club cell abundance in fish exposed to predator cues alone and predator cues combined with club cell alarm substances. With this information, we hope to examine how acidified environments affect the recognition of alarm and predatory cues and whether behavioral changes that result from exposure to acidified environments are inherited transgenerationally.

Specifically, one of these factors is a deficit in nutritional education. Health education is a vital part of improving health. The purpose of this project is to evaluate aspects of the community in Coaling, Alabama that affect it's members' health, and to describe an assessment of the community as a whole. We also will propose an intervention related to health promotion that will be targeted at the children of this community. This intervention, implemented at the school that the majority of the children in Coaling attend, would aim to improve their nutritional knowledge on the subject of reading and understanding food labels. Anthony Curto, Chemistry Faculty Mentor: Elizabeth Papish, Chemistry Analysis of Transformation of Iridium Water Oxidation Catalysts - What is the Nature of the True Catalyst? The Papish Group has found that the use of [Cp*Ir(N,N)Cl]Cl (Cp* = C5(CH3)5; N,N is a bidentate ligand) as a catalyst is highly effective in water oxidation. The group uses both N,N = 6,6'-dhbp and 4,4'-dhbp (where dhbp = C10N2H6(OH)2) and has found that they have been effective when combined with an oxidant but they form an unknown blue species. Using UV-Vis analysis and measuring the absorbance at different concentrations and over time we can gain more information into this unknown substance and help determine whether it is forming nanoparticles or a different homogeneous species. Understanding what is formed will help further investigation of the Iridium complexes and their role as catalysts. 15 *The information presented here is intended to represent exactly what was submitted by the student.

Nicholas Davies, Mechanical Engineering Faculty Mentor: Eric Giannini, Civil, Construction and Environmental Engineering An App for Concrete Mixture Design The design of concrete mixtures is a very relevant science in today's world. Whether it be for streets and driveways, building foundations, or buildings themselves, the procedural approach to designing a concrete mixture is necessary to ensure the concrete can satisfy its requirements.While professionals and their companies have the tools to approach concrete mixture design with ease, the procedure can be difficult and time consuming for students, DIY-ers, and others who may use it. By creating an Android application that can handle all of the calculations of concrete mixture design while presenting a user- friendly interface, the field may be made more approachable by a general audience, and the time spent using repetitive calculations can be drastically reduced. The Android app currently in development allows users to create mixtures by defining desired concrete properties and listing the materials on- hand, then returns the necessary proportions to create the mixture. The specific mixtures created by the user can then be saved and recalled or edited at a later time. Additionally, the saved mixtures can be recalled to perform corrections for varying moisture content of the aggregates. Finally, the app is designed to include tables and charts used for working through mixture design by hand, along with a guide for the use of the app. Following the release of the application, it should be a comprehensive utility used by many students in the concrete field. Paul Davis, Mechanical Engineering Faculty Mentor: David Nikles, Chemistry Nanotechnology in Knee Surgery This project will examine how nanotechnology can be used in the future to aid in reconstructive knee surgery procedures. Injuries to knee ligaments and cartilage are very common and often do not heal on their own. This means that many of these injuries require surgery, which can require lengthy rehabilitation times and are not always completely effective. However, nanotechnology has the capability to improve the effectiveness of surgical repairs to two of the most commonly injured tissues: the meniscus and the anterior cruciate ligament (ACL). Meniscus surgeries often consist of the removal of the damaged portion of the meniscus. This is an inadequate fix that often leads to arthritis in the future. Nanotechnology has the potential to give us a solution to this problem. In the future, doctors may be able to use nanomaterials and meniscal cells from a patient to grow a new meniscus that can then be implanted back into the patient. Nanotechnology can also impact ACL repairs, as it can be used to create synthetic ligaments covered in nanoparticles that prevent the body from rejecting the synthetic implant. Nanotechnology can also be used to aid bone sites in accepting implants, decreasing the rate of implant failure. In the future, nanotechnology may give us the tools to reduce the rehabilitation time of an ACL repair surgery to half of what it is now.
